It comes on the week the group posted full year results, in which it sounded an upbeat note on prospects, despite posting a £5.2bn annual loss due to a writedown of its Indian operations, while revenue fell 4.4% to €47.6bn, in part due to foreign exchange headwinds and regulatory headwinds in Europe.
Vodafone said it saw organic adjusted core earnings growth of between 4% and 8% in fiscal year 2018, boosted by stabilising average revenue from its contract customers and lower spending.
Free cash flow (FCF) is expected to reach €5bn from €4.1bn in fiscal year 2017 and €1.2bn the year before.
Barclays notes that the group's valuation looks 'broadly up with events', but that FCF growth beyond 2018 will likely be tempered by rising competitive intensity.
